What is the proper way to clear super-global variable in PHP?
Is this way correct?
$_GET = array();
Or should I use this way?
foreach ($_GET as $k => $v) {
unset($_GET[$k]);
}

2You don't. Or it would be weird and useless if your try to, because those are automatic created variables, see: http://php.net/manual/en/language.variables.superglobals.php – Rizier123 Dec 09 '16 at 15:45

2Or `unset($_GET);`. But why? – AbraCadaver Dec 09 '16 at 15:45

FYI, that dupe applies to all superglobals – Machavity Dec 09 '16 at 15:46

1Short answer: Both suggested ways should work. Longer answer: Just don't. There must be a better way to solve whatever it is you need to solve. – apokryfos Dec 09 '16 at 15:46

Don't use global variables. Global variables are evil. Save your parse $_GET in your own array use it instead of global var. – lamik Dec 09 '16 at 16:01
